JOHN STEPHEN SOUTHERDEN, OF BRISBANEYQUEEN SLAND, AUSTRALIA.

LINE SPACER FOR TYPE-WRITING MACHINES.

' No. 886,433. I

Specification of Letters Patent.

Patented-May 5, 1908.

' Application filed Ifebruary 20, 1906. Serial No aoaoai.

This invention relates to mechanism for v 0 crating the platen of a type writing ma- 0 me its object being to provide simple and effective means whereby the space between the lines of the type writing is'not limited to fixed distances but can be varied to an distance within the operating range of evice and whereby when the same is at rest, the

platen is free to be rotated ineitherdirection.

The inventionconsists in the general con- 'struction arrangement of parts and combination of devices as hereinafter described and illustrated in the accompanying drawings in which the reference letters indicate like parts in all figures. I

Reference bein made to the drawings; Figure 1 is an end elevation of the device attached to the platen of 3. Remington pattern machine. Rig. 2 plan of the same. Fig. 3 end elevation on. enlar ed scale with frame of ma chine removed. ig. 4 part sectional front elevation of right hand end of platen.-

A is the platen, B a disk screwed on to the end of same, B boss formed integrally with disk, 0 a double grip ended clutch adapted to the ta' piece C}. p

In the center of the clutch C is an oblong hole which fits over the boss B this allows movement. of the clutch for grip ing or releasing the disk B. The clutch (5 is held in position by a collar E secured to the boss B.

D' is a ever slotted at top end at D as shown in Figs. 1 and 3 and formed into an eccentric at its lower end pivotally connected by in F totail iece 0, its upper end is pivota connecte by thumb screw G to an arm H, t e other end of which is pivotally connected to the u right arm Iof the operating spacing lever o the machine.

J is a flat spring secured by cltilp K to the tail piece of the clutch C, adapts to engage periphery of the disk,- provided with l with the eccentric D and push the same into gri 1ping contact with disk B.

, i is a stop fixed to the frame of the machine against which the end of the tail piece C rests.

To the end of the platen spindle N is a finger wheel P for rotating the platen forwards or backwards when clutch C is out of grip, when same is in grip the rotation of the platen is controlled by the position of the arm H, in the slotted end D of the lever D and also by an adiusting screw Q screwed u into a threaded ho e in the upright "arr'nT,

TVhen the operating s acing lever is at rest and the tail piece 0 of t e clutch C is in contact with the stop M, the gri ends of the clutch are disen aged from t e disk B as shown by dotted 'nes Figs. 1 and 3, and the platen can be freely rotated in either directionl pfi finger wheel P, when the spacing lever is p e pushes the eccentric ended lever D forward, the eccentric end i) and the grip ends of the clutch C engage with the disk B and the platen is rotated the distance allowed by the adjustment of the arm Hand the adjusting screw Q.

The tail iece 0 comes to its restposition on stop M efore the operating spacing lever of the machine thus releasing the clutch from grippin and the spring of the spacin lever is ofsu cient strength to overcome t e spring J fixed to tail mac 0. a

T e various arts of the machine are not indicated by ref erence letters as they form no part of the invention and are simply illustrated for showin the adaptability of the invention to a macfii tern, I would also have it understood that the invention may be incorporated with other machinesby modifying the arrangement of parts without departing from the spirit of the nvention.

Having now described my invention, what I claim as new and'desire to secure by Letters Patent is 3- '1. In improvements in line spacers for type writin machines the combinatlon of a platen,

- a disk avin a central boss, a friction clutch member, acc lar securing the said member to d towards the operator the arm H returns to its rest position 1 ne of the Remington patthe boss, a lever havin an eccentric end,'a I engages withsaid stop, an eccentric ended tail iece on the clutc member, a s ring level-,2 spacing lever, and an arm pivotally fitte to said tailpiece and enga ing wit the connecting the eccentric ended lever to said.

eccentric end of said lever and eeping said spacing lever.
